Monel, trademarked by Special Metals Corporation, comprises a group of rustless (stainless) metal alloys, primarily composed of nickel (up to 67%) and copper, with some iron and other trace elements. Because it hardens quickly, Monel is difficult to machine.

Monel’s properties:

  • Resistant to corrosion and acids, and some alloys can withstand a fire in pure oxygen
  • High tensile strength
  • Some alloys are completely non-magnetic
  • Typically much more expensive than stainless steel
